Progressive Rate Springs

This Timbren Suspension Kit has hollow rubber springs to deliver a progressive spring rate. The more weight you put in your Silverado or Sierra that pushes down on the rubber Timbren springs the harder they work to prevent the rear end from sagging. Whether you're towing a heavy trailer or carrying a heavy load in the bed of your Silverado or Sierrra, the rubber hollow springs adjust automatically to keep the vehicle level at all times.

This Suspension Kit replaces the factory jounce bump stop on the frame of your Silverado and Sierra. It's unique, progressive design ensures superb ride quality, loaded or unloaded. There should be a 1" gap between the rubber Timbren spring and your trucks axle to ensure unloaded ride quality. Once you hook up your trailer or add a load to the back of your Silverado or Sierra truck, the springs will engage and help support the weight. Unlike some other helper spring options the SES Suspension Upgrade guarantees the best of both worlds.

Customer Q&A - Timbren GMRCK25D


I have a 2016 Chevy Silverado 3500hd crew cab and will be periodically hauling a slide in camper, not all the time though. Which SES system would be best for my truck, the normal set or the severe service product.

Asked
Due to the higher center of gravity a slide in camper is regarded as severe service and Timbren recommends the GMRTT35D for your truck when a slide in is used. The extra spring rate of the severe service Aeons helps combat the sway that occurs with the camper loaded. Since they do not contact the axle when you are unloaded they will not change the ride quality.
